Overview
A Universal Power Supply forms the backbone of an off-grid electrical system.
Definition/Concept
This is a combination inverter, converter, pulse-width modulation current controller, and high frequency power supply for applications from off-grid power, charge controllers, to power supplies for welders, induction furnaces, and plasma cutters.
A large range of power electronic devices is desirable within the infrastructure of communities. Having an individual power supply for each is redundant and expensive. A modular UPS construction kit is desirable as an analogue to the 'industrial-strength Lego' that we have already demonstrated for heavy mechanical hardware infrastructures.
Inverters
An inverter is an electrical device that converts DC voltage from batteries to AC voltage for off-shelf electrical tools and appliances.
Off-the-shelf inverters have about a 2 year lifetime, and 5-10 year lifetime for higher quality models. Lifetime design inverters with plug-in replacement components are required for sustainable communities which use battery storage as a component of their electricity infrastructure. One of the few other feasible, non-battery, non-fuel energy storage may be via heat storage coupled to thermoelectric generators, or possibly thermal storage via phase-change salts and heat engines.
